What do you call your friends in math class?

This joke is a play on words combining “algebra,” a branch of mathematics dealing with symbols and the rules for manipulating those symbols, and “bros,” a slang term for brothers which is often used to refer to close male friends. The term “AlgeBROS” humorously suggests a camaraderie or brotherhood among friends in the context of a math class, specifically one that involves algebra. It plays on the idea that these friends share a bond as strong as brothers through their mutual experience of studying algebra together, turning a subject that can sometimes be seen as dry or challenging into a source of shared identity and fellowship.
